Pearson’s correlation coefficient (r) is used to measure the strength and direction of the linear relationship between two variables, ranging from −1 (perfect negative) through 0 (no linear relationship) to +1 (perfect positive). It is found by dividing the covariance of x and y by the product of their standard deviations, which standardises the result into that fixed −1 to +1 range. It needs at least two pairs, and the result is undefined if either variable never changes. It needs at least two pairs, and the result is undefined if either variable never changes. It needs at least two pairs, and the result is plotted with its best-fit line. It needs at least two pairs, and the result is undefined if either variable never changes. It needs at least two pairs, and the result is plotted with its best-fit line.Worked example:Enter paired x and y values in the same order; the two lists must have the same number of values.Worked example:Enter paired x and y values in the same order; the two lists must have the same number of values.Worked example:Enter paired x and y values in the same order;Enter paired x and y values in the same order;Enter paired x and y values in the same order;Enter paired x and y values in the same order;Enter paired x and y values in the same order;Enter paired x and y values in the same order;Enter paired x and y values in the same order;Enter paired x and y values in the same order;Enter paired x and y values in the same order;Enter paired x and y values in the same order;Enter paired x and y values in the same order;Enter paired x and y values in the same order;Enter paired x and y values in the same order;Enter paired x and y values in the same order;Enter paired x and y values in the same order;Enter paired x and y values in the same order;Enter paired x and y values in the same order;Enter paired x and y values in
